DRI Ranges

DRI stands for Detection, Recognition and Identification and is based on the widely used Johnson's criteria.

  • Detection Detect if an object is present
  • Recognition See what type of object it is (i.e. person, vehicle, airplane)
  • Identification For example see if someone is a friend or foe
Detection Recognition Identification
Rabbit 529 meters 132 meters 66 meters
Person 1862 meters 465 meters 232 meters
Vehicle 4509 meters 1127 meters 563 meters
